SFASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 694,816, dated March 4,1902.

Application filed J' une 10, 19701.

To all wiz/m t may 0011.057412,..-

Be it known that I, Gus WILFRED ANDER- SON, a citizen-of the UnitedStates, residing at Bloomington, in thecounty of McLean and State ofIllinois, have'in-vented a new and useful Sash-Lock, of which thefollowing is a specification. Y

The invention relates to improvements vin sash-locks.

The object of the present invention is to improve the construction ofsash-fasteners and to provide a simple, inexpensive, and efflcient onedesigned to be mounted on the top of the lower 'sash at one side of awindow` and capable of simultaneously engaging the upper sash and thewindow-frame, whereby the sashes are securely held in their closedposition.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a horizontal sectional view of a portion ofa Window provided with a sash-fastener constructed inY accordance withthis invention. Fig. 2 is a plan view, partly in section, the top of thecasing being removed. Fig. 3 is a vertical sectional vienr on the line 33 of Fig. 2. Fig. 4 is a de-l tail perspective view` of the oscillatoryplate or lever. Fig. 5 is a detail view of one of the bolts. Fig. 6 is adetail view of the exterior grip or handle.

Like numerals of reference designate corresponding parts in all the tigures of the drawings.

1 and 2 designate sliding bolts arranged at right angles to each otherand mounted Within suitable Ways of a casing 3 and adapted to besimultaneously reciprocated by a plate or lever 4, which is 'pivotallymounted Within the casing. The casing, which may be constructed in anysuitable manner, consists,

preferably, of a bottom plate 4 and a top or cap 5, which receives thebottom plate and which is secured tothe same by screws f or othersuitable fastening devices 6, which also secure the sash-fastener to thetop of a lower sash 7, as clearly illustrated in Fig. 1 of theaccompanying drawings. The reciprocating bolts are' provided at theirinner edges with 4reciprocating bolts 1 and 2.

Serial No. 63,964. (No model.)

Anotches 8 and 9, and they have lugs or studs face, as clearly shown inFig. 4. The enf `largement 16 forms projecting 4portions or lugs 17 and18 for engaging the notches of the plate or lever engages the studs and11 to l extend the bolts, and the projections or lugs of the lower faceof the plate or lever engage the notches of the Vbolts to return thelatter. The boss 14 is rounded, as clearly illustrated in Fig of thedrawings, to assist in pivoting the plate or lever, which is provided atits upper face with an annular boss or enlargement 19, having oppositeprojections or lugs 2O to engage corresponding Vrecesses 21 of anexterior handle or grip 22. The handle or grip 22, which is adapted tobe oscillated to reciprocate the bolts, is arranged on top ofthe casing, and it is rigid with the pivot}15, which extends through the casingand the oscillaf tory lever. The pivot has its lower end threaded forthe reception of a nut, and a washer is preferablyinterpos'ed betweenthe nut and the bottom plate of the casing.

The annular boss or enlargement 19 of the upper face of the plate orlever forms a support for a spiral spring 23, which is interposedbetween the plate or lever and the handle or grip to hold the former inproper position with relation to the sliding bolts, and the interlockingengagement of the lugs 20 and the opposite recesses 21 permit a limitedmovea ment of the plate or lever on the pivot sumcient to hold the saidplate or lever against the bolts without disengaging the same from thegrip or handle. Y Y

The upper sash 24 is provided ywith a suitable socket 25 and thewindow-frame is provided With a similar socket 26, and these sockets areadapted to receive the engaging outer ends of the bolts when the latterare extended, as, indicated in Fig. 1 of the draw ings. When the grip orhandle is oscillated, it carries with it the plate or lever, whichreciprocates the sliding bolts to carry them into and out of engagementwith the upper The oscillatory- IOO sash and the Window-frame. Bymounting the sash-fastener on the topof the lower sash and engaging theupper sash andthe windowframe it Will be apparent that both sashes aresecurely held in their closed position.

It Will be seen that the sash-fastener is simple and inexpensive inconstruction, that it is strong and durable, and that it is adapted tobe readily mounted on the lower sash of a window and is capable of beingeasily operated to reciprocate the sliding bolts. It Will also beapparent that the sliding bolts are simultaneously reciprocated and thatwhen in engagement with the nppersash and the window-frame they firmlylock the sashes against movement.

What I claim isl. A sash-fastener comprising a casing, reciprocatingbolts provided at their side edges with notches and having studs,`anoscillatory plate orlever mounted in the'casing and provided Wthopenings to receive the studs and having eccentric enlargementsforengaging the notches, and means for operating the plate or lever,substantially as described.

2. A sash-fastener comprising a casing, reciprocating bolts providedwith notches and having studs, an oscillatory plate or lever havingopenings to receive the studs and provided With projections arranged toengage the notches, said plate or lever having a perforation andprovided at opposite sides of the same With lugs, an exterior grip orhandle having recesses receiving the lugs and provided with a pivotpassing through the perforation of the plate or lever, and a springinterposed between the plate or lever and the grip or handle,substantially as described.

3. A sash-fastener comprising a casing, reciprocating bolts, anoscillatory plate or lever engaging the bolts and having a perforation,said plate or lever being provided at the perforation with an annularenlargement and having lugs extending therefrom, an eXterior grip orhandle having recesses to receive the lugs, and provided With a pivotpassing through the perforation, and a coiled spring disposed on theannular enlargement and interposed between the plate orlever and thegrip or handle, substantially as described.

4. Asash-fastener comprisingacasinghaving a tapering boss 14,reciprocating bolts, a plate or lever connected with the bolts andprovided with a flared opening to receive the boss 14 and having anannular enlargement provided With lugs, agrip or handleprovide'd withrecesses to receive the lugs and having a pivot passing through thecasing and through the said opening, and a coiled spring disposed on theannular enlargement and engaging the plate or lever and the grip orhandle, substantially` as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.
